finally, this paper discusses and analyzes the chosen of parameters and close-loop characteristic of dynamic matrix control 本文還對動(dòng)態(tài)矩陣控制的參數(shù)選擇和閉環(huán)特性進(jìn)行了討論和分析。
first of all, it is devoted to discuss the open-loop characteristics and the nonlinear bifurcation analysis and the maneuver ability for the super-maneuverable flight nonlinear model of the new generation fighter . then a flight control system is designed in analytical dynamical inversion method based on the time-scale separation principle 首先,對新一代殲擊機(jī)超機(jī)動(dòng)飛行的非線性模型的開環(huán)特性、分叉特性及機(jī)動(dòng)能力進(jìn)行分析,并以此模型為基礎(chǔ),采用基于時(shí)標(biāo)分離原則的動(dòng)態(tài)逆控制方法設(shè)計(jì)了新一代殲擊機(jī)的飛行控制系統(tǒng)。
based on the mathematic model of oct, it is proved that oct is of the open loop characteristic, which for the first time explained the reason why oct itself can not meet the demand of precision used in practice . since it is impossible for oct itself to realize a close loop structure, the only way to improve the precision of oct is with the help of the new independent variables 從模型化分析出發(fā),在基于光學(xué)電流傳感原理的oct的完整數(shù)學(xué)模型和系統(tǒng)特性方框圖的基礎(chǔ)上證明了oct的開環(huán)機(jī)理,首次從理論上解釋了外界因素導(dǎo)致光學(xué)電流傳感的測量精度始終達(dá)不到實(shí)用化要求的原因在于oct具有開環(huán)系統(tǒng)特性,而且,從oct本身是不可能實(shí)現(xiàn)閉環(huán)結(jié)構(gòu)的。
